Global crude oil and lease condensate production increased 24%, or over 14 million barrels per day (bbl/d), between 1980 and 2010 (click animation above). Although the Middle East was the largest regional producer and grew by 23% over that period, or over 4 million bbl/d, the region's share of global crude oil production was at 31% in both 1980 and 2010. Central & South America, Africa, and Asia grew most rapidly, increasing their combined share of total crude oil production from 23% in 1980 to 32% in 2010.

North America's crude oil production decreased about 1 million bbl/d between 1980 and 2010—the only region with declining crude oil production. As a result, North America's share of global growing oil production fell from 20% in 1980 to 15% in 2010.

Percents on graph represent that region's share of global crude oil production in that year. Percents do not sum to 100% for each year because Oceania was not included in the graph, which only accounted for 1% of global production each year. Download CSV Data

More recently, however, the United States has reversed a decades-long decline in crude oil production. North Dakota and Texas led recent U.S. crude oil production gains. Average annual production, which dipped below 5.0 million bbl/d in 2008, climbed to 5.4 million bbl/d in 2009 and 5.5 million bbl/d in 2010, with 2010 volumes representing an 11% increase over 2008. In October 2011, preliminary data showed that U.S. crude oil production averaged 5.8 million bbl/d.

North Dakota. According to the North Dakota Department of Mineral Resources (DMR), the state's oil production averaged 488 thousand bbl/d in October 2011, more than four and one-half times its October 2005 level. The DMR reported further increases for November 2011, with production averaging 510 thousand bbl/d. North Dakota currently trails only Texas, Alaska, and California among oil-producing states.

Texas. Oil production in Texas has also increased in recent years. The state's oil production, which fell by an average of 1.4% annually between 2000 and 2008, increased 1.7% in 2009 and 5.7% in 2010. From January 2011 through August 2011 (the most recent month for which EIA reports data for Texas), oil production averaged 1.35 million bbl/d, up 15.6% from the 2010 daily average.
